LUMBER BRANDING AND REBRANDING MACHINE FOR PLANING-MILLS AND ROLLER- BEDS.

Specification of Letters Patent.

Patented May 25, 1920.

application filed. July 31, 1916. Serial No. 112,418.

To all whom 2'25 may concern Be it known that I, Josnrrr Gr. McDon- OUGH, a citizen of the United States resident of Eau Claire, county of Eau (dlaire State of Wisconsin, have invented certain new and useful Improvements in Lumber Brandin and 'Rebrandin Machines for Planingills and Roller- Beds, of which the following is a specification.

It frequently happens that dressed and dried lumber and timber will disclose checks or other imperfections and necessitate trimming the ends or cutting a piece of lumber in two or more parts which had previously been branded at the saw mill. This retrimming or cross cutting usually eliminates the original brand and the present object of my invention is to provide a machine by means of which dressed or re-trimmed lumber may be branded orre-branded.

Other objects of the invention will appear from the following detailed description.

The invention consists generally in various constructions and combinations, all as hereinafter described and Y particularly pointed out in the claims.

In the accompanying drawings forming part of this specification,

Figure 1 is an elevation of a branding or re-branding machine embodying my invention,

Fig. 2 is a vertical sectional view of the same, showing the position of the parts in the. operation of re-branding a piece pf lumber,

Fig. 3 is a plan view,

Fig. 4 is a transverse sectional view, showing one of the lumber carrying tables and the mechanism for raising it to separate the abutting ends and permit branding of the piece of lumber on the adjacent table,

Fig. 5 is a similar view, lookingin the opposite direction, showing the clamp device for gripping the piece of lumber while it is being branded,

Figs. 6 and 7 are detail views of the inking mechanism for the branding wheel.

In the drawing, 2 represents the frame of the machine, above which is a hanger 3 supporting a saw arbor 4 and the trimmer saw 5 driven through a belt 6. Beneath the saw is a platform 7 on which the lumber is supported and in said platform I arrange tilting tables 8 placed end to end, hinged at 9 to the platform and forming substantially a continuation thereof, the abutting ends of the tables being free to move vertically to raise the end of one piece of lumber out of alinement with the other piece or to provide room for the branding device. These tables, the branding wheels and the operating mechanism therefor are substantially the same in construction and operation and I will designate them by the same reference numerals, with the addition of the exponent a, and I will describe the construction and operation of one mechanism, it being understood that the other operates in a similar manner.

A link 10 is attached to the table 8 and to a lever 11 pivoted intermediate to its ends on the frame and having a counter balance 12 of sufficient weight to substantially oifset the weight of the table and facilitate lifting the same. 13 is a treadle lever, pivoted at 14 and pivotally connected by a link 15 with the lower end of a rod 16 that is slidable in guides 17 on the frame. The rod 16 has a shoulder 17 positioned to contact with a collar 18 that projects under the table 8 for raising it and separating the piece of lumber thereon and the upper end of the rod 16 is provided with an arm 19 which overhangs the table 8 and the piece of lumber so that when the treadle lever 13 is forced downwardly this arm will bear on the piece of lumber and clamp it securely on the table. A walking beam 20 is pivoted at 21 on the frame and has a slot and pin connection at 22 with the rod 16 to be drawn down at that point when said rod is depressed and the opposite end of the beam 20 has a similar connection with the rod 16 to elevate it and its connections on the downtion of the treadle has therefore the effect of clamping the piece of lumber on one table preparatory to the branding opera tion and raising the other table and the lumber out of the path of the branding wheel. Should it be desired to brand the piece of lumber on the table 8 then the treadle lever 13 will be depressed and the operation described will be reversed; that is, the rod 16 will be raised and with it the table 8, while the rod 16 willbe depressed to, clamp its lumber on the table 8 Beneath the tilting end of the table 8 is a shaft 23 mounted transversely of the machine in bearings 24. This shaft is provided 7 said shaft and also revolve on its axis. This] Wheel is provided on its peripheral face I with branding marks or characters 28, preferably repeated on the surfaceof the-wheel nes t -b etl i the tables is raised, sniiic entspace s .p roi'or {the branding wheel beneath. ,that' thegl mber was dressed or man U .and from .wh ch: it as sh pped to the builder Y .vi ded with an operating lever 25 and is free to rock in said bearingsand also has an axial movement therein. Upon this shaft a bracket 26-is secured a'nda branding Wheel 27 is monnted'on said brachetto 1 00.: with to provide for asuccessionkn marks on the end of the piece 0f -lu 11 1bel, and the brands 1 n which M11391? mt d gn t the mil aotured or dealerf Normally, this branding ngh eel,
